Expansion Microscopy of Synaptic Contacts on the Mauthner Cells of Larval Zebrafish

open access: yesBio-Protocol
Because of its genetic tractability and amenability for live imaging, larval zebrafish (Danio rerio) have emerged as a model to study the cellular and synaptic properties underlying behavior.

ANK1 and EPB41 Variants and The Risk of Glucocorticoid‐Induced Osteonecrosis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.

Balloon purpura

open access: yesInternational Journal of Pediatrics & Adolescent Medicine, 2021
Valsalva maneuvers have the potential to cause dermal capillary rupture manifesting as purpura and petechiae. We present a unique case of Valsalva purpura occurring in a 12-year-old girl after blowing up multiple balloons at a birthday party. Obtaining a

Effective Performance of the 2022 American College of Rheumatology/EULAR Classification Criteria for Antineutrophil Cytoplasmic Antibody–Associated Vasculitis in Pediatric Patients: An ARChiVe Study

open access: yesArthritis &Rheumatology, EarlyView.
Objective To assess the 2022 American College of Rheumatology (ACR)/EULAR classification criteria for antineutrophil cytoplasmic antibody–associated vasculitis (AAV) in children with chronic small‐to‐medium vessel vasculitis. Methods A cohort of 574 patients, identified by physician's diagnosis (MD‐diagnosis) in A Registry of Childhood Vasculitis, was ...

A novel method for estrous cycle staging using supervised object detection

open access: yesNPP-Digital Psychiatry and Neuroscience
The estrous cycle regulates reproductive events and hormone changes in female mammals and is analogous to the menstrual cycle in humans. Monitoring this cycle is necessary as it serves as a biomarker for overall health and is crucial for interpreting ...

The components of an electrical synapse as revealed by expansion microscopy of a single synaptic contact

open access: yeseLife
Most nervous systems combine both transmitter-mediated and direct cell–cell communication, known as ‘chemical’ and ‘electrical’ synapses, respectively. Chemical synapses can be identified by their multiple structural components.

The relationship between ADAMTS13 genotype and phenotype in congenital thrombotic thrombocytopenic purpura and characterisation of ADAMTS13 mutants [PDF]

open access: yes, 2015
Congenital thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy, usually involving ADAMTS13 gene defects. ADAMTS13 processes the multimeric plasma glycoprotein Von Willebrand factor making it less reactive to platelets.

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

From Interferon Signature to the Clinical Landscape: Type I Interferonopathies

open access: yesArthritis &Rheumatology, EarlyView.
Objective TypeI interferonopathies are heterogeneous diseases driven by dysregulated type I interferon (IFN‐I) signaling. Diagnosis is challenging due to clinical/molecular variability and the need for IFN‐I quantification. The aim of this study was to characterize the clinical, immunologic, genetic, molecular profiles of patients with suspected ...

Translational control of auditory imprinting and structural plasticity by eIF2α

open access: yeseLife, 2016
The formation of imprinted memories during a critical period is crucial for vital behaviors, including filial attachment. Yet, little is known about the underlying molecular mechanisms.
